Highball Alloy

The Highball has been out bombing the competition at races since it was brought into commission.

Taking the swift and light intent of our 29" wheeled carbon Highball and crafting it out of aluminum, we've added a couple very notable other features: value and versatility. The proprietary aluminum tubing allows for a strong, respectably light frame, and features the same responsive geometry as our carbon race bike. There are some swank new rear dropouts that allow riders the option of running a fixed position for geared use, or a pivoting, adjustable dropout for single speed use. Clean lines and super-versatility aside, this is also one of our most affordable bikes, redefining the notion of "bang for your buck".


  • 29" wheels
  • Sizes: S, M, L, XL
  • 135mm rear axle spacing
  • Standard or Direct mount rear derailleur option
  • 73mm threaded BB: creak-free riding and easy installation

Can I mount a chainguide to my bike?

Yes, this bike was designed to easily accept a BB mount chainguide. For a more XC setup, you can use top-only guides like the MRP 1x or e13 XCX. For full chainguidance, we recommend the E13 LG1 Tr, MRP Lopes guide or Mini G SL. For dual ring guides, try the E13 TRS+Dual or MRP 2x guides. These should fit with minimal or no modification.

Is there an option to make this bike a single speed?

Yes- single speed dropouts are available for purchase on our webstore. They accept a standard 135x10 hub.

What fork sizes are recommended?

We recommend a 100 or 120mm fork. 100mm will be better if you want a quicker, more XC feel- while 120mm will offer a more forgiving ride and stability.

What is the torque spec for the seat collar?

We don't provide a torque spec for the seatpost, because it really depends on what seatpost you are using. Some seatposts are slippery, and require more torque to stay put, and others are very thin- and can be crushed by overzealous tightening. Some are both slippery and thin...
You will not damage your frame by overtightening the seat collar, assuming you have a 30.9mm seatpost in it.

What kind of front derailleur do I need?

This bike uses a 34.9mm Bottom Swing (high clamp), Top Pull front derailleur.

What kind of headset does this bike use?

We use a headset generally referred to as "mixed tapered". This is a 44mm internal upper cup, with an external 49mm lower cup. The SHIS name is ZS44/28.6 EC49/40.

What kind of rear brake adaptor do I need?

This frame uses a standard IS rear brake mount. Just pick your rotor size and order the correct adaptor to go from IS to post mount (all modern brakes).

What q-factor should I use for the cranks?

On any crank with optional Q-factor, choose the wider version.  166 for Sram XX, or 168 for XX1.  For Shimano doubles, we recommend the M980.  

What size bottom bracket shell does this bike use?

We use a standard 73mm threaded BB. Nearly any crank on the market (besides BB30 cranks) will fit.

What size rear hub do I need?

This bike uses a standard 135x10mm quick release rear hub.

What size seatpost do I need?

We use a 30.9mm seatpost. Always ensure it is inserted into the frame a minimum of 100mm (4").

Why does this frame use a standard thread-in bottom bracket, when many of your competitors use press-in style (BB30, Pressfit 30, BB90, BB92, BB86)

It is true that there are some slight weight savings available with the various pressfit bb designs (exact weight savings obviously vary depending on system, frame manufacturing techniques, and crank model), but we don't feel this small savings make up for the inconveniences. We are still able to make a frame that is lighter than most of our competitors, while still using a heavier bb system. There are a number of disadvantages that exist with press fit systems:

1) Special installation and removal tools are required for these parts, including a headset press. This is not convenient for most home mechanics, and they are quite expensive. Traditional external BB's can be installed or removed with a simple $10 hand tool.

2) "Permanently installed cups". Shimano doesn't recommend removing and re-installing their press in bb cups (as they may become damaged), so moving parts from bike to bike is no longer an option.

3) Creaking or shifting bb's can be common with these systems. Since the bearing is pressed into a cup, which is then pressed into the frame- it can be hard to get all of the press fits snug- without being too tight on the bearing or too loose in the frame.

4) Reasonable tube sizes. One of the most commonly claimed advantages of a larger bb shell is the larger diameter downtube that goes with it. This may be an advantage on road bikes, where tubes can be incredibly thin and large for optimal stiffness. On a mountain bike, this area of the frame sees a lot of abuse from rocks and crashing, and needs to have a certain amount of wall thickness to survive actual use. Using what we consider a "safe" wall thickness and carbon layup, and a fairly typical tube diameter, we get an exceedingly stiff, light, durable product. If we used a larger downtube, we would either have a heavier frame (same wall thickness but larger diameter), or a less durable product (thinner walls and larger diameter).

5) Chain clearance. Take a look at some of our competitors frames with press in bb shells. The down tube comes so close to the chainrings that many frames have chainsuck guards on the downtube! In our mind, the chain should be able to fall off on a mountain bike and not get jammed between your crank and thin-walled carbon downtube.

6) Backwards compatibility: Many of our customers purchase a frame and build it up with their choice of parts, or parts from an old bike. By using a standard bb, we are compatible with everything without requiring confusing adaptors.

7) Chainguide compatibility: While it may seem strange to talk about putting chainguides on a short travel bike, it is becoming more common now with 10 speed drivetrains. Thread in bb's mean the frame is compatible with bb mount chainguides. We like versatility....
